AtoNs can be integrated with automatic identification system (AIS). AIS transmitted form an actual aid (buoy, lighthouse etc.) is termed a "real AIS AtoN".

The automatic identification system ( AIS) is an automatic tracking system that uses transceivers on ships and is used by vessel traffic services (VTS).

The height of the light above the chart datum for height (usually based on high water ). e.g. 15m for 15 metres. The range in which the light is visible, e.g. "10M" for 10 nautical miles. An example of a complete light characteristic is "Gp Oc (3) W 10s 15m 10M". This indicates that the light is a group occulting light in which a group of three ...
